Establish new all-day high frequency service from Wood Island to Chelsea, Everett, Malden (T104)

"Service every 15 minutes or better 7 days a week 5:00 AM to 1:00 AM" "Route T104 improves to all-day high frequency service; extends to Chelsea and Blue Line and replaces part of 112; does not serve Everett Sq - Sullivan; depending on SLX Alternatives Analysis, may be combined with SL3 via Chelsea Station in the future."
